HAY-RETAINER FOR HAY-STAGKERS.

Specification of Letters Patent.

Patented Dec. 7, 1915.

Application filed April 22, 1914. Serial No. 833,718.

To all *w/iom it may concern Be it known that we, RALPH M. BAKER andJOHN DATUS, citizens of the United States, residing, respectively, atAlliance and ester-ville, in the counties of Box Butte and Custer, Stateof Nebraska, haveinvented certain new and useful Improvements inHay-Retainers for Hay-Stackers; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to hay stackers, and has particular reference toa hay retainer therefor.

The principal object of this invention is to. provide a simple device ofthis character which will prevent the hay being withdrawn from thestacker upon withdrawal of the sweep rake.

Another object is to provide such a device of this character and simplemeans for releasing the retainer, so that the stacker may dump the loadof hay on the stack.

Other objects and advantages will be apparent from the followingdescription andwith particular reference to the accompanying drawings.

In the drawings: Figure 1 is a side elevation of the lifting rake of astacker. Fig. 2 is a top plan view thereof. Fig. 3 is a front elevation,partly broken away. Fig. 4 is an enlarged fragmentary section of therotatable portion of the retainer. Fig. 5 is an enlarged detailperspective view of the support, and showing the means for holding thearm.

Referring particularly to the drawings, 10 7 represents the frame of astacker, which includes the side bars 11, to which the elevat-, ing fork12 is secured. Secured to each of the side bars 11 of the frame is avertical bracket or support 13, in which is pivotally mounted the rearend of an arm 14. Both of the arms extend forwardly to a point directlyover the free end of the fork l2. Directly in front of each of thebrackets or supports 13 is a vertical member 15, provided with avertical series of openings 16, and a vertical elongated slot 17 throughwhich the inner end portion of the arm 14: is adapted to play. Each ofthe brackets 13 has an attaching foot 18. Cross pins 19 are adapted tobe inserted in the openings 16 of both of the brackets 15 tolimittheswinging movement of the arms 14. Extending transversely acrossthe free end of the fork, and mounted on the outer ends of the arms latis a shaft 19 carrying thereon a plurality of cylindrical drums 20, toeach of which is secured a plurality of radially extending arms 21, forengagement by the hay as it is placed on the fork. 19 is secured aratchet wheel 22, which is adapted to be engaged by a spring pressedpawl 23 mounted on the adjacent arm 14, suitable connections 24Lextending from the pawl to a point within convenient reach of theoperator. The pawl may be raised from engagement with the ratchet teethby means of the connections 24 to permit the shaft to rotate in onedirection, for the release of the load of hay. The pawl and ratchetmechanism permits the shaft to rotate as the hay is forced in on theelevating fork, but pres vents it rotating in the opposite direction,until released by the operator. This prevents the hay being withdrawnfrom the fork while the rake is depositing a load thereon. As the sweeprake advances to the stacker, the hay will engage the radial arms 21from beneath the shaft 19, and rotate the shaft. When the rake iswithdrawn from the stacker, andthen backed off, the pawl preventsretrograde movement of the shaft and arms and thus holds the hay andpermits the sweep rake to be withdrawn, the cable 24 being pulled torelease the pawl 23 so that the hay will slide from the rake under thearms 21 and rotate the shaft in the opposite direction, when the stackeris lifted to deposit the hay on the stack.

\Vhat is claimed is:

1. The combination with a hay stacker including an elevating fork, of ahay retainer comprising supports mounted at the inner end of the fork,arms pivoted'on the supports and extending to the outer end of the fork,a rotating shaft on the arms, hay retaining arms on the shaft, and meansfor holding the shaft against rotation in one direction.

2. The combination with a hay stacker including an elevating fork, and aframe to which said fork is attached, of a hay re tainer comprisingsupports mounted on the frame at the inner end of the fork and onopposite sides thereof, arms pivoted to the supports and extending overthe outer end On one end of the shaft 0f the fork, a rotatable shaft'j'ourna'led in the outer ends of the arms, means for pre venting theretrograde movement of the shaft, radially extending hay engaging armson the shaft, and adjustable meanson the supports for engagement withthe shaft supporting arms-for limiting the pivotal movement of the shaftsupporting arms.

7 Copies of this patent may be obtained for five cents each, byaddressing the In testimony whereof, We affix our signatures, in thepresence of two Witnesses.
